digital clock with date and temperature

Hello guys !
I've searched on the google without success looking for an allready made arduino based digital clock who shows also the date and temperature . I do not know where to search anymore. The problem is I'm not such a good programmer and I would like to build for my company such a clock.

If the clock can be made on an 16 x 24 led matrix it will be much better.
If not , the 4 x 7 segment display it will be enought.

Thanks an advance for understanding and support.

Hm, the best available solution i could think of was to use a HD44780 based Display (2x20 or 4x20 characters) together with a DS18B20 temperature sensor and a DS1307 Real time clock.
For each of the parts you can get quite useful examples of how to use them here if not complete libraries.

I know ! The hd44780 is not an option. I like to put the clock on the company parking. If it will be with led matrix I can insert some advertising text or some other text like:

If temperature low - Drive carefully !
If temperature high - some tips for driving carefuuly on high temperatures.

If can not be made with led matrix it will be ok even with 7 segments digits.

Thank you very much for the response.

in that case i think there are multiple ways of using a lcd matrix - but i have never used one myself before.. (or anything but hd44780)

The other stuff though should be ok i hope ;0)
